Canadian Data Report of Fisheries and Aquatic Sciences
Data reports provide a medium for filing and archiving data compilations where little or no analysis is included. Such conipilations commonly will have been prepared in support of other journal publications or reports. The subject matter of data reports reflects the broad interests and policies of the Department of Fisheries and Oceans, namely, fisheries and aquatic sciences.
Data reports are riot interidcd for general distribution and the contents must not be referred to in otl ie~ piiblic;itions uithout prior written authorization from the issuing establishincnt. 1 Iic correct citation appears above the abstract of each report. Data reports are abstracted in Aqrratic Sciet~c,e.s ar7cl Fi.sher.ies Abstracts and indexed i i i the Department's annual index to scientific and technical publications.
Numbers 1-25 in this series were issued as Fisheries and Marine Service Data Records. Numbers 26-160 were issued as Department of Fisheries and the Environ- ment, Fisheries and Marine Service Data Reports. The current series name was intro- duced with the publication of report number 161.
Data reports are produced regionally but are numbered nationally. Requests for individual reports will be filled by the issuing establishment listed on the front cover and title page. Out-of-stock reports will be supplied for a fee by commercial agents.
Rapport statistique canadien des sciences halieutiques et aquatiques
Les rapports statistiques servent à classer et à archiver les compilations de données pour lesquelles il y a peu ou point d'analyse. Ces compilations auront d'ordi- naire été préparées à l'appui d'autres publications ou rapports. Les sujets des rapports statistiques reflètent la vaste gamme des intérêts et des politiques du ministère des Pêches et des Océans, c'est-à-dire les sciences halieutiques et aquatiques.
Les rapports statistiques ne sonl pas destinés à une vaste distribution et leur contenu ne doit pas être mentionné dans une publication sans autorisation écrite préalable de l'établissement auteur. Le titre exact paraît au-dessus du résumé de chaque r a p p ~ r t . ~ L e s rapports statistiques sont résumés dans la revue Résutîîés des sciences aquatiques et halieutiques, et ils sont classés dans l'index annuel des publica- tions scientifiques et techniques du Ministère.
Les numéros 1 à 25 de cette série ont été publiés à titre de relevés statistiques, Ser- vices des pêches et de la mer. Les numéros 26 à 160 ont été publiés à titre de rapports statistiques du Service des pêches et de la mer, ministère des Pêches et de l'Environne- ment. Le nom actuel de la série a été établi lors de la parution du numéro 161.
Les rapports statistiques sont produits à l'échelon régional, mais numérotés à l'échelon national. Les demandes de rapports seront satisfaites par l'établissement auteur dont le nom figure sur la couverture et la page du titre. Les rapports épuisés seront fournis contre rétribution par des agents commerciaux.

q u a n t i t a t i v e ; i n a d d i t i o n t o d e n s i t y va lues , e s t i m a t e s o f biomass (as ash-
free dry weight) and caloric content are given in Tables 136-142. These
have been derived from determinations of dry weight using factors given by
Wacasey and Atkinson (1987). Species not represented in these stations but
found in the four non-quantitative stations listed above are presented in
Table 143.
A composite species list for both areas dealt with in the report has
been compiled in Table 1 and for convenience has been placed immediately
preceeding Part A. A total of 434 species are listed: 33% were common to
both areas, 26% were found only in the Beaufort Sea-Amundsen Gulf
collections and 41% were taken only in the Bathurst Inlet-Dease Strait
samples. The apparent differences between the two regions are at least in
part due to the quantitative sampling carried out in the latter, resulting
in the retention of many more smaller species than in the former. A more
balanced comparison of the two areas may be obtained by referring to
previously published reports on extensive quantitative sampling conducted in
the Beaufort Sea (Wacasey et. al. 1977) and the Eskimo Lakes (Wacasey 1974).
Some of the material presented here has already been treated in a
number of publications which, in addition to those mentioned above, are
listed under References. The names of some species reported in these papers
have here been changed to conform to recent literature, but the former name
is given in parentheses. Identifications of species not covered in previous
publications were made by the authors and others in order to present
complete listings of the benthic invertebrates collected at each station.
Many of the specimens have been deposited in the National Museum of Natural
Hi story, Ottawa.
